..We analyzed seven TE families in four natural populations of each species to tease apart the effects of mating system, demography, transposition, and selection in determining patterns of TE diversity...

..Overall, we propose that TEs are subjected to weak selection, the efficacy of which varies as a function of demographic factors. Thus, demographic effects could be a major factor driving distributions of TEs among plant lineages...
